- the method 700 can comprise circulating, by one or more circulation blowers 110 (e.g., comprised within the oven 100 ), the air heated by the fan friction to generate an airflow.
- the one or more circulation blowers 110 can propel the heated air into one or more circulation corridors 108 extending within the oven 100 .
- the one or more circulation blowers 110 can generate an airflow of the heated air that can traverse into and/or adjacent to the one or more processing chambers 106 .
- the oven 100 can heat one or more items within the one or more processing chambers 106 by via the airflow of heated air (e.g., air heated by fan friction and propagated into the one or more processing chambers 106 by one or more circulation blowers 110 ).
- the method 700 can comprise monitoring, by one or more temperature sensors 116 , a temperature within the one or more processing chambers 106 .
- the one or more temperature sensors 116 can be located within the one or more processing chambers 106 and/or can be operably coupled to one or more temperature controllers 118 .
- the one or more temperature controllers 118 can receive one or more electrical signals from the one or more temperature sensors 116 regarding the temperature within the one or more processing chambers 106 and/or can receive one or more inputs from a user of the oven 100 .
- the one or more inputs can regard a desired temperature change to the one or more processing chambers 106 .
- the method 700 can also comprise modulating the temperature within the one or more processing chambers 106 based on the monitoring by the one or more temperature sensors 116 by controlling the fan friction independent of the airflow within the oven 100 .
- the one or more temperature controllers 118 can be operably coupled to one or more motor speed controllers 120 , which can further be operably coupled to one or more second motors 114 powering the one or more heating blowers 102 .
- the one or more motor speed controllers 120 can control the operation of the one or more heating blowers 102 via the one or more second motors 114 .
- the one or more motor speed controllers 120 can control operation of the one or more heating blowers 102 to increase the amount of heat generated by fan friction.
- the air within the oven 100 can be heated to a greater degree and the airflow generated by the one or more circulation blowers 110 can propel the heated air throughout the oven 100 (e.g., into the one or more processing chambers 106 ) to increase the temperature within the one or more processing chambers 106 to the desired temperature.
- the one or more motor speed controllers 120 can control operation of the one or more heating blowers 102 (e.g., via the one or more second motors 114 ) independent of operation of the one or more circulation blowers 110 .
- a temperature within the one or more processing chambers 106 can be varied (e.g., via modulating the one or more heating blowers 102 ) by the one or more motor speed controllers 120 while maintaining a constant airflow (e.g., generated by the one or more circulation blowers 110 ).
- the temperature within the one or more processing chambers 106 can be modulated independently of the airflow within the one or more processing chambers 106 .
